IMPROVBD BRICK AND TILE MACHINE.

"dlp Srlgrbnlc ninna tu in ilgrsc trturs gntrut mit mating infini ille samt TO ALL WIIOM IT MAY CONCERN:

Be it known that we, JAMES II'OTCIIKISS and Ez-RA BUss, of Springfield, in the county 4of Clark, and` State of Ohio, have invented an Improved Brick and Tile'Maehinc; and we do hereby declare that the following is a full andexact 4description thereof, reference being had to the accompanying dra-wings, making part' of this spccilication- Figure l being a top View of the machine.

Figure 2, a top view thereof, the pug-mill beingremovcd.

Figure 3, a longitudinal vertical section in a plane indicated by the ligne :e z', fig. 1.`

Figure 4, an vend view of the part of the machine shown in iig; 2, showing the die-plate, Src.

Like letters designate corresponding parts in all of the figures. v

n this machine we employ a reciprocating piston or plunger, L, which moves ina close box or boxes,- M, and at everyr forward movement drives the clay out` through a die or dies thereby to be formed for 'either bricks v or tiles and afterward to be cut into proper lengths. Weprepare the clay and feed it tothe plunger-box or boxes by means of a pugmill, B, situated above said plunger-box or boxes. This pug-mill may be 'of ordinary construction, with suitable working'arms D D and inclined wing E, or theequivalent thereof, for forcing vthe clay down into the plunger-box or boxes through an opening, m, in the bottom of the puglmill. 4'.lhe shaft C of the pug-mill extends down through the plunger-box, or, if there are two, between them, as shown in the drawings, there being a solid `division strip, Q, separating the boxes, through which the shaft extends, as shown most clearly in fig. 2. The shaft thus extended below the plunger-boxes is provided there with a crank, G, by

means of which the plunger L is moved.; and in the means by which the working connection is made between this shaft or its crank `and the plunger lies an important feature of our invention, as follows: The plunger is provided with a rod, beam, or guide-frame, I, extending back a considerable comparative distance, Vsay to an extent in proportion to the other dimensions of the machine about as represented in the drawings, and the frame A of the machine is extended in that direction far enough to furnish a support and guide to the plnngenbeam.

A connecting-rod, H, connects .the crank G with the outer or roar end of the plunger-beam, being pivoted to i the latter by a wrist or pivot-pin, z, as shown in iig. 3. This extension of the plunger-beam, and connection between it and the driving-crank or shaft to so long a distance, enable us.to drive the plunger by the pug-mill shaft with no intermediate gearing, and at the same time produce very little side friction or strain on the plunger, since the greatest angle made between the'conneeting-rod H and 4plunger-beam I is comparatively small, as indicated in igsfl and 2. The plunger L and as much of its beam I as necessary are divided t0 receive the division strip or partition Q. The die-plate R has the required ydies se in it, as seen in tig. 4.

The whole machine is exceedingly simple, strong, and effective.

What we claim as our invention, and'desire to secure by Letters Patent, is

1. The extension of thc pug-mill shaft C down through the plunger-box, and providing it with a crank, G, or its equivalent, below, so as to drive the plunger thereof, substantially as herein specified. y

2. We also claim the solid division strip Q separating theplunger-box into the compartments M M, `and in connection therewith the division of the plunger L into two parts striding the said division strip and the pugmill shaft, substantially as herein set forth.

3. We also claim the extended plunger-beam I and'connecting-rod H pivoted tothe outer end of the said: plunger-beam, arranged and operating together substantially as and for the purpose herein specified. V

The above specification of our improved brick and tile machinesigned by us this eighth day of April, 1867.
